| 1 | Yolk-shell nanoarchitecture for stabilizing a Ce_(2)S_(3)anode显示文摘Rare-earth sulfides are of research interest for lithium-ion batteries(LIBs)due to their abundant lithium intercalation sites and low redox voltage.However,their electrochemical performances are not satisfactory because of poor conductivity and volume change upon electrochemical cycling.Herein,nanoarchitectures ofγ-Ce_(2)S_(3)encapsulated in a hollow mesoporous carbon nanosphere(Ce_(2)S_(3)@HMCS)are fabricated using the self-template strategy combined with the in-sphere sulfuration method and tested as an LIB anode.The void space between the Ce_(2)S_(3)core and the outer layer of the carbon nanosphere has been properly designed and modulated to achieve excellent electrochemical performance in terms of electronic conductivity,reversibility,and rate capability.The reversible capacity of Ce_(2)S_(3)@HMCS is 2.6 times that of the pure Ce_(2)S_(3)anode,which can gradually increase and maintain a capacity of 282 mAh·g^(−1)at a current density of 1 A·g^(-1),and a high Coulombic efficiency(~100%)can be achieved even after 1000 cycles.This good performance is attributed to the unique yolk-shell nanostructure with a highly crystallized and stable Ce3S2 core and volume expansion buffer space upon lithiation/delithiation.Ex situ X-ray diffraction and nuclear magnetic resonance results indicate that the lithiation of Ce_(2)S_(3)@HMCS is an intercalation process.This study represents an important advancement in precise structural design with in-sphere sulfuration and sheds light on a potential direction for highperformance lithium storage. | Kanglong Hui Jipeng Fu Jie Liu Yongjin Chen Xiang Gao Tian Gao Qi Wei Chengyu Li Hongjie Zhang Mingxue Tang | 2021 | Carbon Energy2021，3，5： | 0 |
| 2 | Preparation of polydopamine based redox-sensitive magnetic nanoparticles for doxorubicin delivery and MRI detection显示文摘To improve the water-dispersity of superparamagnetic iron oxide nanoparticles(SPIONs),a novel polydopamine based redox-sensitive copolymer modified SPIONs were prepared for the biomedical application to deliver doxorubicin(DOX)and magnetic resonance imaging(MRI)detection.The major components of this nanoparticle include SPIONs and the redox-sensitive polydopamine(rPDA)crosslinked copolymer,where N,N-Bis(acryloyl)cystamine served as cross-linker,dopamine methacrylamide and a long-chain polyethylene glyco methyl ether methacrylate acted as comonomers.Here the rPDA@SPIONs were formed by the ligand exchange reaction of dopamine moiety with the oleic acid layer capped on the surface of SPIONs,and the inner area of the nanoparticles formed a reservoir for DOX,while the hydrophilic PEG moiety helped the nanoparticles well-dispersible in aqueous solution.The DOX-loaded rPDA@SPIONs demonstrated a high drug loading efficiency of 857μg DOX per mg iron,and a strong T2 relaxivity of 123 mM-1•S^(-1)for MRI.The drug release analysis of drug-loaded nanoparticles showed a sustained and high cumulative drug release in GSH up to 73%within 48 h,rather than the relatively low release rate of 37%in PBS(pH 7.4)without GSH.All the results showed that the designed magnetic nanoparticle may be a promising vehicle for anticancer drug delivery with stimuli-triggered drug release behavior,and also a foundation for building smart theranostic formulations for efficient detection through MRI. | Le Shang Qiuyue Wang Kanglong Chen Jing Qu Jian-bin Luo Qing-han Zhou | 2017 | Journal of Bioresources and Bioproducts2017，2，2： | 0 |
| 3 | Phosphorous and selenium tuning Co-based non-precious catalysts for electrosynthesis of H_(2)O_(2)in acidic media显示文摘Electrosynthesis of hydrogen peroxide(H2O2)is an on-site method that enables independent distribution applications in many fields due to its small-scale and sustainable features.The crucial point remains developing highly active,selective and cost-effective electrocatalysts.The electrosynthesis of H2O2 in acidic media is more practical owing to its stability and no need for further purification.We herein report a phosphorus and selenium tuning Co-based non-precious catalyst(CoPSe)toward two-electron oxygen reduction reaction(2e–ORR)to produce H2O2 in acidic media.The starting point of using both P and Se is finding a balance between strong ORR activity of CoSe and weak activity of CoP.The results demonstrated that the CoPSe catalyst exhibited the optimized 2e–ORR activity compared with CoP and CoSe.It disclosed an onset potential of 0.68 V and the H2O2 selectivity 76%-85%in a wide potential range(0–0.5 V).Notably,the CoPSe catalyst overcomes a significant challenge of a narrow-range selectivity for transitionmetal based 2e–ORR catalysts.Finally,combining with electro-Fenton reaction,an on-site system was constructed for efficient degradation of organic pollutants.This work provides a promising non-precious Co-based electrocatalyst for the electrosynthesis of H2O2 in acidic media. | Jingxin Xie Lijie Zhong Xin Yang Dequan He Kanglong Lin Xiaoxia Chen Huan Wang Shiyu Gan Li Niu | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
